He appears in the eighth book along with Captain Blunderpants and Harold Hutchins (Alternate Universe).He first appears reading a comic book then changing a sign. He hypnotises Sulu and Crackers to destroy the Good George and Harold and to become really wicked, in their terms. a few chapters later, they get shrunk by the Good George and Harold and get sent back to their Earth.
Because of him along with Evil Harold Hutchins and Captain Blunderpants causing havoc in the City of Piqua in the normal universe, their good counterparts Harold Hutchins, George Beard and Benjamin Krupp aka Captain Underpants have been framed and arrested for the crimes their evil counterparts committed.
Like his friend Evil Harold Hutchins, Evil George is evil. Unlike the Good George, he is the more timid of the pair similar to how the good Harold is in the main universe.
Unlike the Good George from the main universe, he does not wear a tie, but wears a T-shirt instead.
